The Remington Model 10 is a pump-action shotgun with an internal hammer and tube magazine. The Model 10 was manufactured between 1908 and 1929, with a "trench gun" version used during World War I. Like the Ithaca 37, the Model 10 shotgun has no side ejection port, instead loading and ejecting from the bottom port. It was offered in 12 gauge with barrel lengths from 20 to 32 inches (51-81 cm).
